Abstract

A heat and moisture exchange (HME) unit (50) including a housing (52), a heat and moisture retaining media (54) (HM media), and a resistance indicator (56). The housing (52) forms a first port (58), a second port (60), and an intermediate section (62). The intermediate section (62) extends between the first (58) and second ports (60), and defines a flow path fluidly connecting the first (58) and second ports (60). The HM media (54) is maintained within the intermediate section (62) along the flow path. The resistance indicator (56) is carried by the housing (52) and is fluidly connected to the first port (58). In this regard, a visual appearance of the resistance indicator (56) changes as a function of pressure within the housing (52) to visually alert a caregiver as to possible existence of an excessive pressure differential condition within the HME unit (50).
